FELL GAUGE FOR LOOP/IS.

Application filed September To all yiti/m t mayy concer/7i Beitknownvthat I, ABRAHAM lvl-BORN- s'rniN, citizen of the United States,residing at `ljaterson, in the county of Passaic and 5 State ofvNewJersey,have invented certain new and useful `Improvements in FellGauges for Looms, of which the following is a specification. 4

This invention relates to fell gauges for looms, that is to sary, tofell gauges with reference to which the weaver, after the sheet of warpand finished fabric has 'been shifted longitudinally forany purpose, canreset such sheet to bring the fell of the fabric accurately to itsformer position, so that on the weaving heilig proceeded with no blemishwill appear in the goods, such as transverse marks due to too muchspacing from or a crowding with respect to the fell of the next ensuingpick of filling. One of the principal objects of the invention is toprovidea loom with means whereby a fell gaging device will automaticallytake the gaging position upon stopping of the loom and withdrawtherefrom when the loom is againstarted so that it `will be out of theway in the actual weaving.

f In the drawing,

Fig. l is a tcp plan vie-w of the front por- 30 tion of a loom embodyingmy invention;

`Fig. 2 is a plan of a fragment of the sheet of warp and finished fabricand ofthe fell gaging means .and its support;

Fig. 3 is a front elevation of said means; and

Fig. at is a A.side elevation thereof, 'theV breast-,beam appearing insection.

a is the breast-beam below which is arranged, as usual, a controller.member for controlling the driving of the loom, said member hereconsisting of a rock-shaft b `iournaled in the loom frame e and having 7The driving means and the 24, i923. serial No. 664,577.

thrown across the batten by any well-known means.

On the breast-beam is secured hy two screws g or otherwise an elongatedplate It which preferably has two spaced depending rests L, so that it-stands a little above the top surface of the breast-beam. This plateextends lengthwise of the breast-beam and is arranged near thecontroller On the plate, which preferably reaches a trifle over the linecoincident with the nearer margin of the fabric A, and near its innerend is an upstanding screw z' affording a fulcrum for a lever structurewhich may be described as follows: In the form shown this leverstruct-ure is angular, having one arm in the form of a bar j having alongitudinal slot 7" receiving the screw c" (so that the lever structurehas a sliding fulcruin on the screw) and at its inner end an extensionstud j? on which is pivoted, so as to be movable in a vertical plane,the other arm which comprises a socket 7s having the actual ypivotalbearing on the stud and a stem Z which is telescoped into the soeiretand .may be adjusted lengthwise by manipulating a set-screw Wi, the stemterminating in a blade Z whose free end edge is perpendicular to thestem.

On the plate near its outer end is another screw n which affords afulcrum for a lever o which is here a straight bar. Its outer end isadapted to be held normally in tht` path of movement of the controller,i. e., of its handle b', by a spring 7) which connects the lever withthe frame of the loom. The limit of movement of the lever under the pullof the spring is afforded by a pivoting knife-joint connection glbetween its inner end and the adjoining end of bar j) adapted in foldingto present its salient angle toward the hatten.

On the plate, near its inner end, is an upstanding cam 1' the functionof which will appear in the following description of the operation ofthe mechanism:

`When the loom is started running, by shifting the controller handle tothe full-line position in Fig. l, said handle shifts the lever o to theoblique position shown in this figure, which in turn shifts thementioned lever structure also to the oblique position there shown, itsblade Z being retracted from the fell C of the fabric and out of the wayfor weaving. 7iilien the lever structure is cam r and is elevated sothat its free end stands clear of and so cannot bear on and thus produceany possible blemishing of the fabric. lVhen the loom is stopped, byshifting the controller handle to the dotteddine position in Fig. l, thespring p returns lever o and consequently the lever structure to thelimit afforded by the knife-joint connection g (or so that the barsy'and 0 are alined). This brings the free end edge of the blade Zcoincident with the true line of the fell and should the Weaver have anyoccasion for moving the .sheet of Warp B and fabric A he can onresetting the same obtain perfect accuracy as to coincidence of the fellwith its former position `by using the free end edge of said blade as agauge; this is insured partly because the lever structure is now heldagainst a definite` stop (afforded by contact at the knife-jointconnection by the end of bar j with the end of bar o) and partly becausein this position of the parts the pivoted arm of the lever structure hascleared the cam r, allowing said blade to lie upon the fabric.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent is:

l. A loom including supporting means and a system ofV movable partearrangedV loom movable back and fort-h from one to the other of the onand off positions and vice versa and fell-gaging means confined to movewith the controller back and forth and horizontally out of and intofell-gaging relation to the fell-line. y

3. A loom including supporting` means and a system of movable partsarranged therein and including a controller for controlling the startingand stopping of the loom movable back and forth in an upright plane fromone to the other of the on and 01T positions and vice versa andfell-gaging mea-ns confined to move With the controller back and forthand horizontally out of and into fell-gaging relation to the fellline.

il. A loom including supporting means, fel-l-gaging means movable in thesupporting means substantially horizontally from one to the other ofpositions Where it will be in or out of fell-gaging relation to thefell-line and normally held in one of said positions, and a controllerfor controlling the starting and stopping of the loom movable from oneto the other of the on7 and elf positions and vice versa and when movedto one of its said positions to shift the gaging means from one to theother of the said positions thereof. l

5. A loom including supporting means, fell-gaging means movable in thesupport ing means substantially horizontally from one to the other ofpositions where it will be in or out of fell-gaging relation to thefell-line and normally held in one of said positions, and a controllerfor controlling the starting and stopping of the loom having partthereof movable in an upright pla-ne from one to the other of the on andoff positions and vice versa and arranged ,when moved to one of its saidpositions to ABRAHAM M.
